USB-C Dockingstation G5 detects 2. Display but has no Output after replugging the Laptop

[MrScarped]

Hi,

i bought a new HP Envy x360 15-ed Notebook before Christmas and as Dockingstation the G5 USB-C Dock.

After the first setup of my Workplace i pluged-in my Laptop and everything worked fine. Both Display worked and my Keyboard and Mouse worked to until i repluged my Laptop to he Dockingstation. 

The Laptop shows both displays and is extending the Display to the second Display (shown in Win 10 Displaysettings) but the second Monitor shows no Input. (Problem is with HDMI and DisplayPort) 

I can make it work if i keep repluging the display cable into the Dock but only until i replug my Laptop.

With my SurfaceBook the Dock and The Monitor works fine.

But for my Envy i am at my wits end. I hope someone can help me or at least tell me why my HP ENVY x350 15-ed does not work with my HP Dock. As far as the Specs my Envy shoild have true USB-C or am i mistaken?

Best Regards!

@MrScarped 

What is your HP ENVY x350 15-ed ? I'm thinking about your machine is the dock are not fully compatible. HP does not make very clear on the products with USB-C port: what it can and can't do.

For the G5 dock, it requires "For USB-C™ functionality, host PC must support the DisplayPort™ Alt mode protocol through its USB-C™ port. Thunderbolt™-enabled notebooks will function at USB-C™ speeds".

Now you need to check full specs of USB-C port on your machine, again what i it ?

Regards.

Thank you for your quick reply. I have the HP ENVY x360 15-ed0768ng

In the specs it says:

1 SuperSpeed USB Type-C® 10 Gbit/s Signalrate (USB-Stromversorgung, DisplayPort™ 1.4, HP Sleep and Charge)

as far as i know that should support the G5 Dock, or do i mix something up ?

Best Regards
